maennrrc COILING DEVICE.

Application filed April 18, 1927. Serial No. 184,605. g

This invention relates generally to coiling machines and particularly to the type of coiling machines used in steel mills for coiling hot or cold rolled strip steel and commonly 5 referred to as strip reels, the predominant object of the invention being toproduce a reel for a machine of this type which includes novel and improved means whereby the forward end of strip metal may be fixed or attached to the reel at operation, or while s the start of thereeling aidreel is in motion.

Prior to this invention various means were employed in connection with strip reels for securing the forward end of the strip metal to the reel of the machine,

so that said strip metal might be coiled on sald reel, and the most common method was to provide the reel with'one or more slots so that said reel was provided with which the forward coiled was inserted. forward end of the st a' gripping device into end of the strip to be In lieu of the grip the rip was bent or punched,

or in some such manner physically attached to the reel, so as to cause same with without undue to rotate thereslippage. While these methods of securing the end of the strip to the reel were quite common and were reasonably efiicient, they were objected to because it took some little time to properly introduce the end of the strip of met same, and also because coiler be stopped durin taching the strip. creased because of the strip a1 into place and bend they required that the the operation of at- This difficulty was in-' the fact that at this time metal may be hot, and also provision had to be made to take care of the'on-coming strip material, while the forward end portion was at rest during the operation of attaching same to the reel, as the main body of the strip continued tachment of the end to move during the atthereof.

of the strip metal to the-reel, I have devised the improved arrangement disclosed in the present application,

which, briefly stated,

I seen by referring to Fig. 11,

V carried by In view'of the difficulties encountered in comprises associating an electro-magnetwith the reel on which the strip .metal is to beooiled. This electro-magnet is so arranged coiling machine made in accordance with my 7 invention and illustrating fragments of the guiding members associated therewith.

Fig. II is a vertical section on line I I-II ofFigI.

Fig. III is a View similar to Fig. I, but showing the reel as it will appear whenthe strip material has been coiled thereon.

In the drawing, 1 designates a drive shaft of astrip reel provided with a reducedportion at an end thereof to produce an annular shoulder 2, and mounted on said reduced portion of said shaft is myimproved reel A. Thereel A comprises a pair of disks 3 and 4, which are spaced. from each other longitu-. dinally of the reduced portion of the shaft 1, said disk 3 being abutted against the shoulder 2 and the disk 1 being located adjacent to the outer end of the reduced portion of the shaft 1, as shown in Fig. II. Located between the spaced disks 3 and 1 and mounted on the reduced portion of the shaft 1 is a cylindrical member 5 provided with annular flanges 6 at its opposite ends. As will be the spaced disks 3 and 4 and the cylindrical member 5 are provided with keyways into which a key 7,

the reduced portion of the shaft 1, extends so that said disks and said cylindrical member will rotate with said shaft.

Also a nut 1 is arranged on the shaft 1 at the outer end thereof to prevent outward move-.

ment of the disks and member 5 on the shaft.

Associated with the disks 3 and 4 to produce the complete reel is a pluralityof segunderstood, however, that I and to one of the inwardly extended walls 12 of one of said segmental members. Also, each inwardly extended wall 13 of each segmental member is provided a with a lug 14 against which the link 13 associated with said member at that side thereof is adapted to abut, as shown in Fig. I, so that rotary motion will be transmitted from the disks to the segmental members. Supported by the cylindrical member 5 and located between the annular flanges 6 thereof is one or more electro-magnets 15. The magnets 15 preferably are the same in number as the segmental members and also I prefer to give the electro-magnets approximately the same shape as said segmental members. I wish it to be do not limit myself to this arrangement, as reserve the right to ive the electro-magnets any shape which is Iound desirable and also I may employ magnets of a number greater or less than the number of segmental membersemployed. The electro-magnets 15 are secured 1n place in any suitable manner and are, of course, electrically connectedto a source of electrical energy.

Associated with the reel A at the-upper portion thereof is a guide member '16, said guide member being provided with a curved adjacent to" As sug portion arranged immediately the circumferential face of the reel. gested by the position in which it is located in Fig. III, the guide member 16 is capable of being moved to a position remote from the reel, veniently removed from the In the operation of a coiling machinenprovided with my improved reel, the forward end of the strip moved around the reel in such manner as reel.

to cause said strip to come into contact with the peripheral face of the magnetized reel A, as by means of the guiding member 16. The

electro-magnets. which, as stated, are electrically connected to a suitable source of energy, will immediately attract the end of the strip and will draw same into firm contact with the arcuate walls of the segmental members, whereby said end of said strip will be carried around by the reel tated and as the strip of metal is coiled thereon.

When the'coiling of the material has been so that the coil of metal may be coni of metal S to be coiled is as said reel is ro-' completed and it is desired to remove the coil from the reel, the segmental members 8, 9 and 10 are permitted to rotate in the di rection' of the arrow. in Fig. III with respect to the disks 3 and 4. This movement will have the eiiect of swinging the links 13 on their pivots, whereby each of the segmental members will be moved inwardly to reduce thediameter of the reel, whereupon the coil may be removed by the aid of a member which will. pass between the corrugations 19 on the outer faces of the arcuatewalls of the seg: mental members and in this manner will engage t-he lowermost turn of the coil, as well as the other coils thereof.

While I have shown my improved reel as including the structure which permits reduction ofthe diameter thereof to allow the coil to be removed, I do not wish to belimited to this arrangement, as I consider my invention in its broadest aspect to involve. associating an electro-magnet or an equivalent: F

speed of delivery of the on-coming material the motion of the coiler preferably being such that when the forward end of the strip comes into contact with the magnetized reel just enough. pull is exerted on said strip to take up any slack that would a given rate of s denly reduced. caller is in" motion ed having its speed sudand as instant contact is ordinarily result from the material which is being delivered at n other words, becausethe;

a reel of any coxlstruc- 3 made with the forward end of the strip, the r proper tension of the strip will be maintained and hence there will be no interruption in the delivery of the strip.

I claim:

a drive shaft, a reel mounted on said drive shaft, said reel comprising a cylindrical member having annular flanges at its 0 posite ends, disks adjacent to said annular anges, means whereby said cylindrical member and said disks are caused to rotate with said drive shaft, a plurality of segmental members, means whereby said segmental members are pivotally attached to said disks, and a plurality of electro-magnets supported by said cylindrical member, said electro-magnets being of a shape corresponding to the shape of said segmental members and being adapted to attract an end of said metal so that it will be attached to said reel.

A machine for coiling metal, comprising I magnet associated with the core, an outer shell composed of a plurality of segmental members upon which the metal strip is adapted to be Wound, and clamping means adapted normally to maintain the segmental members in a rigid expanded condition and operative to collapse the members, said clamping means including pivoted elements movable independently of said cylindrical core in a direction transversely with respect to the major axis thereof. In testimony that I claim the foregoing I hereunto aflix my signature.
